RILEY OPENS DOOR TO COACHING HEAT AGAIN: Finally, some big news involving a local team executive not having to do with asking if a player's mom was a prostitute! Heat president Pat Riley said today he'll do whatever it takes to make Miami a champion again -- and did not rule out the possibility that could mean him coaching again. Doesn't mean it's likely. But the possibility is out there now. Here is my column on this, online now and shipping to Tuesday's paper. Meantime take a dip in our poll and tell Riley what you think. And tell us why.

DOLPHINS POLL. BECAUSE SPARANO SAYS THE SEASON HAS STARTED: I know it's only May, and barely that. But Dolphins coach Tony Sparano said that to him the weekend rookie camp just ended is the official start of preparation for the 2010 season. So there you have it. Time for an early gauge of what Dolfans are thinking about the coming season. I look at seemingly soft schedule and can easily envision 10 wins. Others are not so optimistic. For example, ESPN's updated, post-draft Power Rankings have Miami slotted an uninspiring 22nd, well back of both the Jets (8th) and Patriots (9th). Where do your expectations fall and why? Remember, it's not what you are hoping for, but what you realistically envision.

DEZ BRYANT'S MOM CONTINUES TO EMBARRASS HERSELF: Angela Bryant is demanding an apology now from Dolphins GM Jeff Ireland over his "was your mom a prostitute" question -- as if his earlier public apology was not all-encompassing enough for her. Well it now is revealed Angela's druggy past was not so much in the past after all. She was arrested in April 2009 for selling crack cocaine to undercover informants and found guilty in August and sentenced to 10 years' probabation. She's lucky she isn't back in prison. Two thoughts here. One, Ireland and the Dolphins have apologized enough. Period. Two, Dez should pay his mother to shut the [bleep] up and not be seen in public. She is an embarrassment. The "was your mom a prostitute" question should be more insulting to prostitutes than to her.

MOMENTUM FOR MAYWEATHER-PACQUIAO: Am told Floyd Mayweather Jr. (pictured) dominated Shane Mosley Saturday night (I missed it; was at a wedding). Now the ultimate bout -- Mayweather vs. Manny Pacquia -- is gaining momentum and should happen. I'm always waiting for the return of the heavyweight division to rescue boxing, but who needs it? I think Mayweather-Pacquiao will set PPV records and remind everyone that the Sweet Science still is embedded in our national psyche in a way that mixed martial arts isn't, and won't be.

ON ARIZONA IMMIGRATION LAW: I'm conservative on illegal immigration. Think it's a big problem and a drain on America's economy. Think we should protect our borders. But even from that vantage, I think Arizona's controversial new anti-immigration law is shockingly over-the-top and must be rescinded. It is racial profiling at its worst. I'm glad to see some of the Diamondbacks' six Latino players speaking out. I think sports can wield some leverage here in helping to nudge Arizona forward into the 21st Century.

IT'S NOW THE EX-FED EX ORANGE BOWL: SportsBusiness Journal reporting today (click here) that FedEx is ending its 21-year run as title sponsor of Miami's Orange Bowl Classic, the longest such partnership of any BCS bowl game. The good news? It's now the splendidly unadorned Orange Bowl Classic, at least temporarily. The bad news? Naming rights are for sale and some new corporate sponsor will jump in soon.

OH, CANADA? NO, CANADA!: Click here for the bizarre tale of Canadian youth-hockey coaches who thought it was roaring funny to give beer to 9- and 10-year-old players after a game. I think this is an outrage. What a waste of perfectly good beer.

FAREWELL, JEFF FEAGLES: Venerable ex-Miami Hurricane finally retires after 22 NFL years. Nobody punted more times (1,713) for more yards. He leaves third in all-time in games played (352). Only George Blanda and kickers Morten Andersen and Gary Anderson played more seasons. Hall of Fame? Doubt it very much. Only two Pro Bowls for Feagles (pitcured). Plus he's a punter! But what a remarkable career. His rookie season was 1988. Recent Dolphins' top draftee Jared Odrick was then not yet 1 and literally learning to crawl.

DEAR GREG...: Your blog's OK but would be better if occasionally you would reprint the ill-fated last menu from the Titanic on the day it sank. Thank you.
